Question

Bar model too please.I don't understand.

Answer 1

2/3*x=7 1/2

2/3 *x=15/2

x=15/2*3/2=45/4=11 1/4

Answer 2

We can quickly change 7 1/2 yards into an improper fraction and divide it by 2/3 of a yard.

 

15/2 / 2/3 

 

We multiply by the reciprocal and get: 

 

15/2 x 3/2 = 45/4 = 11 1/4
